Dolichopus

Dolichopus is a large cosmopolitan genus of flies in the family Dolichopodidae. Adults are small flies, typically less than 8 mm in length. Nearly all species are metallic greenish-blue to greenish-bronze. It is the largest genus of Dolichopodidae with more than 600 species worldwide.

8 occurrences of Dolichopus on record, most of them in the Oligocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

8 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

656 taxa

The Paleobiology Database records 6 sites for Dolichopus, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Entered from

6 references

Each of the 8 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Each entry links to the Paleobiology Database's own record for the work.
